the sicov/kk46 drug open-safety study

Conditions: COVID-19

Summary: this is an open-label, dose-escalation phase i study to assess the safety and tolerability of sicov/kk46 in healthy volunteers. the purpose of this study is to determine the maximum daily dose of sicov/kk46 as a single agent in adult healthy participants. based on preclinical data from this institution, the investigators hypothesize that sars-cov-2 inhibition with sicov/kk46 could potentially reduce pulmonary inflammation, thereby improving covid-19 patient outcomes.

this is an open-label, dose-escalation phase i study to assess the safety and tolerability of single and multiple doses of sicov/kk46 in healthy male volunteers. this study include 3 cohorts received 3.7 mg, 11.1 mg, 22.2 mg of the sicov/kk46, respectively, via inhalation route. all subjects will undergo scheduled safety and tolerability assessments while in the clinical unit and as outpatients to the end of the follow-up period.
